Method - jQuery Mobile

jQuery Mobile is a touch-optimized web framework (additionally known as a JavaScript library or a mobile framework) currently being developed by the jQuery project team. The development focuses on creating a framework compatible with a wide variety of smartphones and tablet computers, made necessary by the growing but heterogeneous tablet and smartphone market. The JQuery Mobile framework is compatible with other mobile app frameworks and platforms such as PhoneGap, Worklight and more.

Cross-platform & cross-device:
The fact that my app worked immediately on both Android and iOS - along with many other platforms  - is a massive advantage. As an individual developer, it is a huge effort to maintain a separate code base for each platform. Writing a quality mobile application for a single platform is a full-time job, having to re-do that for each platform takes a lot of resources. The fact that my app will work on both my Android and iOS devices equally well is a huge bonus.

Furthermore, especially with the massive proliferation of Android devices in all shapes and sizes, making your app look presentable on a huge variety of screen resolutions is a real challenge. For serious Android developers, device fragmentation in terms of screen size (scaling from the downright tiny to quite large) actually represents a considerable development cost. With the browser rendering your application in a way that looks reasonable on every device, you don't have to worry about this to anywhere near the same extent.
